Bad Service from Dstv

Bad service, I called in wanting to downgrade my services & they told me I cant as im on a contract but when I took that contract they said there will be a fee for cancelling the contract & I agreed

Now they are telling me I need to send an sms as the people who are suppose to downgrade me cannot be contacted. I did but till today no phone call and worse they have de activated my services, isn't there an alternative to this Dstv, I think they take advantage as they have no real competitors. Check now my kids can't watch cartoons & I cant downgrade to an affordable package, I keep calling and the call center keeps on finishing my Airtime & they dont even call back, I am just stuck, sick & tired of this poor service.
